The objectives of this clinical trial are the overall performance and safety of the ENDO GIA Staplers with ENDO GIA SULUs with Duet TRS TM.

Condition Intervention
Roux En Y Gastric Bypass Device: Duet TRS

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: A Prospective, Single-Center Investigation of the Safety and Performance of the ENDO GIA Staplers With ENDO GIA Single Use Loading Units With DUET TRS TM in a Gastric Bypass Procedure

Further study details as provided by Medtronic - MITG:

Primary Outcome Measures:
  • Incidence of Adverse Events. [ Time Frame: Day 30 ]

Secondary Outcome Measures:
  • Operating Room (OR) Time [ Time Frame: Day 0 ]
    OR time was captured in minutes, with time starting at the first port placement and concluding at the removal of the last port.

  • Length of Hospital Stay [ Time Frame: Day 2 (Approximately 1.5 days post randomization) ]
    Days spent in the hospital

  • Incidence of Stapler 'Misfires' [ Time Frame: Day 0 ]
    The incidence of stapler misfires was captured as the number of patients with misfires. The types of misfires that were captured were less than B shaped staples, incomplete staple line and stripping of the rack teeth.
